Why Does My Dog... Bark at Nothing?

Dogs bark for all kinds of reasons. They may be alerting you to something noteworthy; making a request (or a demand, depending on your point of view); aggressively warding off (or confronting) prey, predator, or interloper; communicating stress or discomfort; or engaging in play.

Barking might be a response to a howl heard from half a mile away. Or because a squirrel just chattered in the backyard. Or because your
dog wants dinner. Or because you walked in the door and life is just! so! good! In any case, barking is a perfectly normal canine behavior.

Behaviorists categorize barking into these categories:

territorial barking

alarm barking

attention-seeking barking

greeting barking

socially facilitated barking

frustration-induced barking

illness or injury barking

separation-anxiety barking

But some dogs bark excessively, seemingly at the drop of a pin. Luckily, there are measures you can take to help reduce his or her sensitivity and/or the volume and frequency of the response. Talk to your veterinarian, a board-certified veterinary behaviorist, a certified applied animal behaviorist, or a qualified certified professional
dog trainer if you’re serious about stopping the noise.

If you believe your dog is barking at absolutely nothing, compulsive barking is a possibility, especially if your dog barks excessively and repetitively while also moving in repetitive ways. For example, a compulsive barker might pace in a circle or walk back and forth along a fence as she barks.

Thankfully, there’s help for this problem, too. Ask your veterinarian.
